    Tower of Power alarm

    A friend came over tonight with his Early 80's 150 Mercury that has a jet on the lower unit. Says it always had a beep beeping to start and then once running it went away. He says its VRO, and not premix fuel. Does anyone know what this alarm may be all about and why it now doesn't want to...

    Merc 9.9 sneezing

    I have a 92, mostly unused Merc 9.9 and put all new components into the carb as it had been in storage 14 years. Looks brand new. Starts easy, idles beautifully, full throttle lots of power, mid throttle to slower it tends to run about 10 or 15 seconds and then sneeze/miss and pick up again to...

    Mercarb bogging, hard start

    This 84 mercruiser 140 had a "rebuilt" carb put on last year and I adjusted the throttle llinkage to specs and other areas of concern by the book. The engine runs beautifully and sounds great. But, if you don't hold your mouth just right when starting (usually just a little extra throttle)...

    Mercuiser 140 trim issue

    I have a 1984 Mercuriser 140. The control handle is one that you pull out from the side/wall to neutral for starting. It has trim up/down button on the shift handle and tilt/trailer on the wall. Just today the up portion of the trim on the shift handle stopped working, never a problem. So, I...

    One bad compression cylinder does not a complete rebuild make?

    On my 91 3.0 mercuiser with not great compression on all, but only 30lbs on number two. We did a wet test and it only went up a couple lbs. We pulled the valve cover and the valves seem seated ok, but, we'll get a tool to push em out and see how they seat. We saw some small rust/pitting on...

    3.0 Compression problem

    I have picked up a nice boat and trailer and comes with 1991 3.0 Mercruiser. It has a cracked jacket, not block and no oil in engine, so JB'd and have done this before with good results. However, upon doing an initial compression check, all cylindars come up very nearly the same, about 100...

    89 Evinrude Tracker compression

    I have 1989 Johnson 90HP Tracker Pro Series. I did a compression check today, although it had not been started since last summer, and the motor is new to me. The numbers came out all around 75+/- a few lbs on all four. Its a little cold blooded, but once warmed up runs well and starts...

    Merc 140 timing made easy?

    I want to reset the timing on my mercruiser 140. 1. I don't understand why one has to get the special wires to put it into base timing mode vs. just being able to set it at a certain degrees just the way it is? In the old days we just set timing by ear and all was well. 2. What happens if I...

    Mercruiser 140 dropped dropped dead between house and lake

    Today I put new plugs, set the dwell and adjusted the timing on my 140. It ran so sweet that a touch of the key and it fired right up. I took it with a friend to the lake an hour away. Wouldn't fire, nothing. Tried a little starter fluid just in case, but nothing. dead, but cranked over...

    Lots of Oil in Bellows

    At the end of last season, I experienced the engine running at usual RPMs, but, the speed slowing, and after a few miles (I had to get back to shore) and a trip to test it, it got much worse and I quit using it. II thought maybe the coupler was going bad, however, I did not experience...

    93 Evinrude 6HP Throttle adjustment

    When the throttle returns to idle, their seems to be slack in the linkage, or most likely a stretched cable and so at the carburator all does not go back to its idle point, rather, runs too fast. If I manually move it back, it works. How can one tighten the throttle cable, or make it so the...

    93 Evinrude 6HP linkage

    I just got this very nice 6HP evinrude short shaft that has little use and was professionally winterized and stored a few years. I started it and it runs beautifully, but, doesn't want to idle down enough without grabbing the linkage inside the cover and manually backing it down. Is there a...

    Alpha one outdrive ujoint issue

    I removed the drive spline from one alpha one and put on my other, newer outdrive. The newer outdrive looks great inside, however, the ujoint when pushed out showed a kind of grittyness inside the needle bearing caps, not clean and shiny. There seemed no slack or damage in any way, the ujoint...

    79 Johnson 15hp electric start----- shifter problem

    I have a 79 Johnson 15hp and everything starts and works fine, but, when shifting from reverse to forward or the other way.....it is difficult to get it to set in neutral, like it sits on a high point and wants to move off of that point into forward or reverse. Is this is linkage issue or worn...

    Bellows order

    I wanted to know if ANYONE has put the ujoint bellows on AFTER installing the exhaust bellows and if it complicates anything. I am assuming the ideal order is Ujoint bellows installed first, and exahaust bellows after. But, I already installed exhaust belllows and don't want to uninstall them...

    Upper shift shaft removal/exhaust bellows

    Would appreciate some advice on two points. 1. Main Q: I need to take out the upper shift shaft to get exhaust bellows too in. The set screw came loose ok, but what's the next steps to get it removed? Any damage concerns or things to look out for? 2. I already put the exhaust bellows on the...

    Alignment verification

    I asked the top mechanic at a local boat dealership why I should have to realign my engine since the mounts seemed totally solid and it all went exactly back in the way it came out. He claims that in "scores of boats" that he's worked on, only one really needed an alignment due to bad motor...

    Thanks to everyone's good guidance I was able to pull my 140 mercruiser engine and seal rear freeze plug, and on the alpha one gen one,,,,,fix shift cable, install new gimbal bearing (after a 10 hour removeal), and attached just over 1/2 of the NEW bellows procedure. It seems difficult to...
